71V2556S Datasheet (Renesas) - 3.3V Synchronous SRAMs

71V2556S, 3.3V Synchronous SRAMs

The IDT71V2556 is a 3.3V high-speed 4,718,592-bit (4.5 Megabit) synchronous SRAM.

It is designed to eliminate dead bus cycles when turning the bus around between reads and writes, or writes and reads.

Thus, they have been given the name ZBTTM, or Zero Bus Turnaround.

Address and control signals are
